Abstract

A press shoe for a shoe press with extended nip, said press shoe is of combined hydrostatic and hydrodynamic type and has a plurality of hydrostatic pressure pockets (18), each of which is preceded by a leading land surface (19) and followed by a trailing land surface (20) and into which lubricant is supplied under pressure. According to the invention each pressure pocket (18) has a first pocket zone (26) in which a hydrodynamic pressure shall be created and which comprises a bottom surface (28) located at gradually decreasing depth from the concave surface portion (4) of the press shoe (3) seen in the direction of rotation of the belt member (1), said depth being zero at the trailing end (t6) of the pressure pocket (18). The bottom surface forms an angle .alpha. of from 0° to about 2° with a tangent (29) to the concave surface portion (4) of the press shoe (3) at the trailing end (t6) of the pressure pocket (18). Further, the first pocket zone (26) is preceded by a second pocket zone (27) comprising a plane bottom surface (30) forming an angle .beta. of from 0° to about ~ 10° with a plane that coincides with the bottom surface (28) of the first pocket zone (26).
